研究表明，早期性经历和随后的性冒险行为之间存在一致的关系。我们假设，这种关系是由于对行为去抑制(BD)的普遍倾向，BD、早期性行为和随后的危险性行为之间的关系可能受到对男性的共同遗传影响和对女性的共同环境影响。对1512对同性双胞胎青少年(50.2%为女性)进行了前瞻性抽样。青少年BD通过行为障碍、对立违抗障碍和自我报告的犯罪行为的临床症状计数来衡量(14岁)。首次性行为年龄定义为双方自愿的口交或穿透性行为的首次年龄(平均年龄~17岁)。成人危险性行为的定义是过去一年(24岁)在药物和酒精影响下的性行为和随意性伴侣的数量。多变量分析表明，男性14岁BD、性始年龄和成人危险性行为之间存在显著的共同遗传差异，但女性没有。与男性相比，女性在共同环境对这些变量的影响程度上没有显著差异。值得注意的是，对于女性来说，性行为起始年龄与24岁的危险性行为没有明显的相关性。早期性行为和后来的危险性行为之间的关系可以通过对BD的一般易感性得到更好的理解，BD主要受男性遗传因素的影响。14岁BD和性行为开始年龄之间的联系受到女性遗传和环境因素的共同影响；然而，性开始年龄似乎不是成年女性性行为冒险行为的显著预测因素。研究结果表明，旨在减少性风险行为的预防计划可能针对14岁以下表现为BD的年轻人，特别是男性。需要更多的研究来预测女性成人的性行为冒险行为。
Research has demonstrated a consistent relationship between early sexual experience and subsequent sexual risk-taking behaviors. We hypothesized that this relationship is due to a general predisposition towards behavioral disinhibition (BD), and that relationships among BD, early sex, and subsequent risky sexual behavior may be influenced by common genetic influences for males and common environmental influences for females. A prospective sample of 1,512 same-sex adolescent twins (50.2% female) was used. Adolescent BD was measured by clinical symptom counts of conduct disorder, oppositional defiant disorder, and self-reported delinquent behavior (age 14). Age of sexual initiation was defined as first age of consensual oral or penetrative sex (mean age ~17). Adult risky sexual behavior was defined by sexual behaviors under the influence of drugs and alcohol and number of casual sexual partners in the past year (age 24). Multivariate analyses showed evidence for substantial common genetic variance among age 14 BD, age at sexual initiation, and adult risky sexual behavior for males, but not females. There was no significant difference in the degree of common environmental influence on these variables for females compared to males. Notably, age of sexual initiation was not significantly correlated with age 24 risky sexual behavior for females. The relationship between early sex and later risky sex can be better understood through a general liability towards BD, which is influenced primarily by genetic factors for males. The association between age 14 BD and age of sexual initiation was influenced through a combination of genetic and environmental factors for females; however, age of sexual initiation does not appear to be a salient predictor of adult women’s sexual risk-taking behavior. Findings suggest that prevention programs aimed at reducing sexual risk behavior might target youth exhibiting BD by age 14, particularly males. More research is needed on what predicts adult sexual risk-taking behavior for females.
